Dave, there are many available options. If you aren't going to use it often, I suggest asking friends or family if they have one you can loan. If you do buy one. I can recommend the PORLEX hand grinders. I have experience with a few different hand grinders, including Hario, and have to say the Porlex produces the nicest grind and is higher in quality than many others (in it's price bracket). It's also very portable, and being stainless steel in construction, it's ideal for camping (can take a beating).
Try a site sponsor, or ebay. You might be lucky to get a PORLEX as I've heard they had a factory fire which has slowed production recently.
